Claims.

This invention relates to a container.

An object ofthe invention is to provide an inexpensive container forfoodstuils, and beverages which will not impart a foreign taste to itscontents.

Another object oi this invention is to provide a container` suitable forholding oils and greasy substances.

Still another object is the provision of a low priced container suitablefor soda fountain use.

A further object is the provision of alcontainer which may be readilyconverted into a dinner plate.

Known containers are usually made from paper or card-board, waxed ortreated in various ways for the purpose'of waterproofing the container,and in some cases Wax is also used to act as a stiiening and supportingagent. for thin materials.

board taste to their contents, regardless of temperature, and the tasteis particularlynoticeablewhen the containers are used for hot beverages.

It has been found that when ordinary containers are used for a salad,such as chicken salad or any food substance containing an oil or grease,the container quickly becomes saturated with oil'which dissolves the thecontents thereafter have tainer taste.

It has been proposed to use the cellulose product now widely known ascellophane for the purpose of lining containers, but thus far theresults from efforts in this direction have been unsatisfactory owing tothe difficulty of manipulating thin sheets of cellophane, and when seamsor splices are made in this material, they lack the strength andinsoluble qualities of celloa distinctive conyphane. Furthermore acontainer lining of thin cellophane made according to the usualpractice, will not retain its shape and size as will waxed paperlinings.

Accordingly, the present invention has for an object the provision ci alow-priced container having a seamless lining of cellophane or otherthin material, suitably supported so that the lin-- ing will retain itsshape.

It will be understood that when cellophane is referred to hereinafter,that cellophane or any other'materiai suitable for lining purposes willbe meant.

Other objects will appear in the following de scription given with theaid ofthe accompanying drawings of which duced scale.

container formed without cutting, from a pattern such as shown in Figure9.'

Figure 8 is a horizontal section taken through 8-8 of Figure 7.

Figure 9 is a plan view-on a reduced scale of the sides of the containershown in Figure 'l as it appears before'folding.

The invention will nowv be described with the aid of the accompanyingdrawings.

Figure 3 shows an octagonal-shaped piece of 4 cardboard or othersuitable material I having a protective coating, and

circular base section at the center, indicated by dotted line 2, fromwhich a series of regular wings or blades 8 to I0 is formed -by cutswhich radiate from line 2 to the corners of the Octagon.

In constructing this modification of the invention, a sheet o!cellophane or other lining material, octagonai in shape but larger thanthe cardboard, indicated in Figures land 2 by reference character Il, isplaced over the cardboard, so that the latter is centered in respecttothe lining material. It is preferred that the lining` material becemented to corresponding parts of the respective blades or wings Ito I0formed by the cuts in the cardboard at some place off-center,

thus leaving the cellophane unattached /to the opposite half of thewing. This cementing is largely used to aid in retaining the parts inposition during a subsequent folding operation as the structurels suchwhen completed that no cement is required to make the respective partskeep their-shape.

. The cardboard and cellophane are then folded about a suitable mandrel,with the successive wings 3 to i0 overlapping each other, formingregular lfolds I2 of cellophane which are caught between the `by' thewings I Y Figure 5 is a horizontal section taken through overlappingedgesof the shell formed Since the-cellophane octagon was larger thanthe cardboard, edges of the lining will extend beyond the tops of thewings and this edge is folded over lthe outside of the vessel at I3, and

' with any cement preparation. Furthermore, the

shell material may be quite thin, and not necessarily Very strong, asone layer of the material reinforces the others.

Figures d, 5, and 6 show a modification in which the outer shell isformed by four wings I5 to I r8, which are divided by cuts extendingoutwardly from a central portion i9 which forms the base of theicintainer, to the edges of a square. lophane is superimposed on the,cardboard square, the Cellophane square being the larger, and afterbeing cemented together in desired places, the arms and the liningmaterial, indicated generally in the drawings by reference character 20,arel folded upward and curved about a suitable form so that therespective Wings overlap each other retaining tucks 2i of Cellophane 2libetween the wings. As in the case with Figure 1, the excess of liningmaterial is folded over on the outside of the cup l forming an outsiderim d of lining material cardboard 29 with the center or base portionindicated by the reference character 30, from which radiate a series ofdotted lines 32 regularly spaced and extending to the corners of thepiece, While a second series of regularly-spaced dotted lines extend tothe perimeterrof the octa-l gon, in the present embodiment, they areshown as intersectingthe faces at a point ofi center. The dotted linesindicate the places where the cardboard 29 and a larger, similarlyshaped,

piece of lining material 34 superimposed thereon and secured thereto bysui/table means, are to be folded. e

As in the previous cases piece 29, together with the lining material,are formed about .a suitable mandrel and tucks are made where indicatedby the dotted lines, so that the completed article appears Ain sectionas shown in Figure 8. 'I'he excess Cellophane is shown in thisembodiment as being rolled over the edge' An advantage of thisinvention, particularly in the embodiments shown in Figures l and 7,

In this embodiment a square of Celis-that they are especially adaptedfor food conrims might be broken or torn after the container is openedin order that the shell and lining material might be spread open to agreater or less extent, whereupon the container will be in effect, anoctagonal food plate, the partially open folds made during thev originalforming of the container serving to keep the parts in a concavecondition. Awire loop, indicated by dotted. lines and referencecharacter 36 shows an arrangement for breaking the rim.

What isclaimed is:

l. The method of making a container which comprises superimposing alayer of lining material over a piece of cardboard having a plurality ofcuts radiating from a central` base section, and forming the sides ofthe container by bending the-sections of the cardboard formed by thecuts upward so that the respective sections overlap each other andsupport tucks formed in the lining material, and thereafter folding saidlining material over .the edge of the cardboard in the form of anannular ring.

2. The method of making a container which comprises dividing a regularlyshaped geometric figure of container material by cuts extending from theedges thereof to a central section to -be l used for a. base, thensuperimposing lining material of greater area than said gure thereon,then forming the sides of the container by bending the sections formedby the cuts so that they overlap each other and retain tucks of liningmaterial, and thereafter forming a rim on the outside of the containerfrom said lining material.

3. The method of making a container which ycomprises dividing aregularly shaped geometric figure by cuts extending from the edgesthereof to a central section to beused for a base, then superimposinglining material of greater area than said figure thereon, then formingthe sides of the container by bending the sections formed by the cuts sothat they overlap each other and retain tucks of lining material, andthereafter forming a breakable rim on the outside of the container fromsaid lining material.

4. A container comprising an outer shell consisting of a plurality offlaring, overlapping Wings integral with a base section, a seamless langular-shaped tucks retained by said-overlapping wings, and a ring onthe outside of said shell at the top thereof formed integral -with saidlining materiai, 'means associated with said ring for lbreaking the samewhereby said container can be converted into a dinner dish.
